JAMES HIRAM LEMONS, OF CEDAR HILL, TENNESSEE, ASSIGNOR T0 3'. S. ADAMS0F CEDAR HILL, TENNESSEE.

POWDER-GUN.

T0 allwhom it may concern:

Be it known that I, JAMES H. LEMONS, a citizen of the United States,residing at Cedar Hill, in the county of Robertson and State ofTennessee, have invented certain new and useful Improvements in Powder-Guns, of which the following is a specification, reference being had tothe accompanying drawings.

This invention relates to certain improvements in powder guns and hasrelation more particularly to a device of this general characterespecially designed and adapted for use in the spraying of plants withinsecticides, and it is an object of the invention to provide a noveland improved device of this general character including means wherebythe requisite discharge of the powder is obtained through the medium ofan air current.

Another object of the invention is to provide a novel andimproved deviceof this general character including a reservoir with which communicatesa delivery pipe, together with a fan coacting with said pipe in a mannerto withdraw the powder by suction from within the reservoir and whichfan also operates to provide an eifective distribution of the powder asthe same is discharged.

It is also an object of the invention to provide a novel and improveddevice wherein the parts are assembled in a manner to permit the same tobe readily carried by the operator with convenience and facility.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved powdergun whereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:

Figure 1 is a view, partly in longitudinal section and partly inelevation, of a powder gun constructed in accordance with an embodimentof my invention.

Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed May 14, 1919. Serial No. 297,005.

Fig. 2 is a fragmentary sectional view taken substantially on the line22 of Fig.1.

Fig. 3 is a sectional view taken substantially on the line 83 of Fig. 2,and

Fig. 4 is a sectional view taken substantially on the line 44 of Fig. 1.

As disclosed in the accompanying drawings, R denotes a reservoir hereindisclosed as substantially cylindrical in form and which is provided inits side wall with a filling opening 1 normally closed by the cap orplug 2? At a point substantially diametrically opposed to the opening 1,the side wall of the reservoir R is provided with a second opening 3 incommunication with an end portion of a suction pipe 4. The reservoir Rand pipe 4 are secured one to the other and preferably through themedium of the attaching plates 5.

The opposite end portion of the pipe 4 is secured to the fan casing C ata point eccentric to its axial center and which casing has its opposedflat faces disposed on an angle of substantially forty-five degreesrelative to the axis of the pipe 4 and inclined inwardly of the pipe 4at the side thereof at which the reservoir R is arranged. The peripheralportion of the casing C is provided with a substantially tangentiallyarranged discharge nozzle "6- and the inner end portion of said nozzle 6gradually merges into the casing C proper so that the material which isdrawn from the reservoir R throughthe pipe 4 by the fan blades B passesthrough the path of travel of said blades before discharging through thenozzle 6, whereby the discharge of said material is in a condition toobtain an effective deposit upon the plants or the like to be treated.

The. outer face of the casing O is provided with an outstanding bearing7 through which is directed a shaft 8. The shaft 8 extends within thecasing C and the inner end portion. thereof is rotatably supported by abearing 9 carried by the inwardly converging arms 10 suitably secured tosaid outer face of the casing C. The shaft 8 extends inwardly beyond thebearing 9 and radiating from said inner or extended portion are theshanks 11 of the blades B. r

v The outer end portion of the shaft 8 has fixed thereto a frictionwheel 12 which is engaged'with the face of the driving wheel 14. Thedriving wheel 14 is fixed to a shaft 15 rotatably supported by theoutstanding bracket 16 carried by the outer face of the casing C. Theshaft 15 also has engaged therewith an operating crank 17 whereby therequisite rotation may be imparted to the wheel 14 for driving the fan.

The end portion of the pipe 4 adjacent the reservoir R is open so thatupon operation of the fan, the desired suction is creatcd therethrough.In order to control the feed ing of the material from the reservoir Rinto the pipe 4, a rotatable sleeve or valve 18 is snugly fitted withinthe open end portion of the pipe 4 and is provided in the wall thereofwith an opening 19 adapted to register with the opening 3 in the wall ofthe reservoir R. By properly rotating the sleeve 18, the opening 3 maybe completely closed or opened as desired. To facilitate the desiredrotation of the slee ve 18, the outer end portion thereof is providedwith the intersecting and radially directed rod 1 or member 20.

The outer face of the casing G is provided with a radially disposed tubeor conduit 21 in communication with the bearing 7 to provide meanswhereby the shaft 8 may be conveniently lubricated. The tube or conduit21 extends in substantially the same general direction relative to thepipe 4 as the reservoir R.

Supported by the inner face of the reservoir R and a peripheral portionof the casmg C is an elongated tube 22 substantially in parallelism withthe pipe 4 and terminating outwardly of the casing C. Disposed throughthe tube 22 is a shaft 23. The shaft 23 extends within the reservoir Rand is continued by a lateral extension or arm 24 whereby the contentsof the reservoir R are effectively agitated upon rotation of the shaft23.

The shaft 23 also extends beyond the outer end of the tube 22 andsecured to this extended portion is a friction disk 25 in contact withthe wheel 14, whereby said shaft 23 is rotated by the wheel 14 in unisonwith the shaft 8.

The opening 3 has disposed thereacross a screening element 26, hereindisclosed as a reticulated fabric, and which element serves to preventthe passage through the opening 3 of material which is not comminuted.

In practice, it is preferred that a suitable body harness be engagedwith my improved device, but as this harness forms no part of my presentinvention, a description and illustration thereof are believed to beunnecessary.

In use, it is also preferred that the device he supported by the leftside of the operator with the pipe 4 substantially horizontally disposedand the reservoir R extending upwardly at a position at the rear. Whenso arranged, the crank 17 may be conveniently operated. This positioningof the device results in the same being well balanced and with a minimumof strain on the operator.

My improved gun is primarily intended for use to spray or distributeinsecticides upon plants or the like, but it is to be understood thatthe same can be employed in connection with other material and for otherpurposes as the necessities of practice may require.

From the foregoing description, it is thought to be obvious that apowder gun constructed in accordance with my invention is particularlywell adapted for use by reason of the convenience and facility withwhich it may be assembled and operated, and it will also be obvious thatmy invention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the. several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim:

1. A gun of the class described comprising a fan casing having adischarge nozzle in connection with its peripheral portion, fan bladesrotatably supported within the casing, means for rotating the fanblades, a suction pipe connected to the casing and in communicationtherewith through a side wall thereof, the opposite end portion of thepipe being open, a reservoir supported by the open end portion of thesuction pipe and at one side thereof, said reservoir being incommunication with the suction pipe, an elongated member supported bythe reservoir and casing, said member being substantially in parallelismwith the suction pipe and spaced therefrom, said member being tubular,a' shaft extending through said tubular member, and an agitating armwithin the reservoir and carried by the shaft, said shaft being indriven connection with the means for rotating the fan blades.

2. A powder gun adapted to be supported by the operator and comprising acasing provided with a discharge in communication with the peripheralportion of the casing, fan blades rotatably supported within 120 thecasing, a suction pipe in communication with the casing through a sidewall thereof, and at a point inwardly of the blades, said suction pipebeing also in communication with the atmosphere, a reservoir mounted 125upon said suction pipe and in communication therewith at a pointinwardly of the communication of the suction pipe with the atmosphere,and means carried by the cas ing for rotating the fan blades.

3. A powder gun adapted to be supported by the operator and comprising acasing provided with a discharge in communication with the peripheralportion of the casing, fan blades rotatably supported within the casing,a suction pipe in communication with the casing through a side wallthereof, and at a point inwardly of theblades, said suction pipe beingalso in communication with the atmosphere, areservoir mounted upon saidsuction pipe and in communication therewith at a point inwardly of thecommunication of the suction pipe with the atmosphere, means carried bythe casing for rotating the fan blades, a member connect- 51 ing the fancasing and the reservoir, and a shaft disposed through said member and.provided with an agitating arm arranged within the reservoir, said shaftbeing in driven connection with the means for ro- 20 tating the fanblades.
